Abstract
Abstract Electrode blocks are compressed in a vertical mold open above and below by close-fitting upper and lower compression members, the mold and the upper compression member being vertically movable by piston drives. A charging container is laterally movable by a horizontal piston drive from a position on a bracket at one side of the press, in which it receives the granular material to be compressed from a dosage device, dropped in from above. The lateral drive pushes the charging container into the center of the press when the press is open to receive it, so that it can discharge its contents into the mold, after which the container is withdrawn with the help of piston driven flaps opening one side of the container so that it may be removed while the upper compression member is approaching its working position. A piston driven guide sleeve is provided to cover the gap between the dosage device and the charging container when the charge of granular material is dumped from the former to the latter, which occurs during the working stroke of the driven compression member which causes the mold and the support bracket for the charging container to be moved downward.

Claim 1
Independent Claim
271 words
A block molding press particularly suited for forming block electrodes by compression of granulated material mixed with a binder comprising, in combination with a press frame: mold means open above and below; an upper and a lower compression means fitting into said mold means respectively from above and below; actuating means for moving said mold means and at least one of said compression means vertically with respect to said press frame; a dosage device (18) for said granular material; a laterally movable charging container (16) movable between a position below the discharge of said dosage device and a position above the upper opening of said mold means (2) and having an openable wall (25), said charging container means (16) also being open above and below and being slidably supported on a surface flush with the top of said mold means (2) provided by bracket means (15) affixed to said mold means (2); lateral drive means (17) for laterally moving said charging container (16) for charging said mold means (2) and expelling a previously pressed block in synchronism with operation of said actuating means; and operating means (27) connected to said openable wall (25) for opening and closing said wall and for maintaining said wall in open or closed position as required in synchronism with the operation of said actuating means and said lateral drive means, said actuating means and said lateral dRive means being so synchronized that one of said compression means protrudes at least part way into said charging container (16) before said charging container is moved away from its said position above the upper opening of said mold means.
